JEEP WRANGLER UNLIMITED 2019 Owner handbook (in English)

Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
Once A Month Or Before A Long Trip
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of coolant reservoir,
brake master cylinder and power steering
and fill as needed.
• Check all lights and other electrical items
for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.Required Maintenance Intervals
Refer to the Maintenance Plan on the follow-
ing pages for the required maintenance inter-
vals.

NOTE:
Once you have carried out the last interven-
tion in the table, continue with the scheduled
servicing, maintaining the frequency indi-
cated in the plan by marking each operation
with a dot or dedicated note. Simply restart-
ing the maintenance from the start of the
plan may cause the allowed interval to be
exceeded for some operations.

**** The spark plug change interval is mile-
age based only, yearly intervals do not apply.
***** This maintenance is recommended by
the manufacturer to the owner, but is not
required to maintain emissions warranty.
WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Severe Duty Conditions
Change the engine oil and engine oil filter at
every 4500 miles (7,500 km) or 6 months if
using your vehicle under any of the following
severe duty conditions:• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.
• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for engine oil
replacement.
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the instru-
ment cluster odometer and a single chime
will sound, indicating that an oil change is
necessary.Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions can
cause the change oil message to illuminate
as earlier than specified. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).
NOTE:
•The actual interval for changing engine oil
and replacing the engine oil filter depends on
the vehicle usage conditions, and is signaled
by the warning light or message in the instru-
ment cluster. In any case, it must never ex-
ceed two years. If the vehicle is used mainly
for city driving, change the engine oil and
filter every year.
•Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
213

•The timing and accessory belts must be
changed every 37,500 miles (60,000 km) or
3 years for particularly demanding use (dusty
areas, severe weather conditions, very low or
very high temperatures for extended periods,
city driving, long periods of idling). Under no
circumstances should these intervals be
exceeded.
Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior
lights.
• Control and recovery of additive level for
AdBlue Diesel emissions (UREA) (if
equipped).Demanding Vehicle Use
• Restore additive level for AdBlue Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
